on my time. i want to get specific. i've been theetret cal all morning. i gave one specific example of the shrimp supply chain. i want to say to that the entire logic and reasoning of why that shrimp exists in bangladesh, it is only 18 years old and that is because of climate change. rising sea levels and then the landowners realize that shrimp is less labor intensive than rice. if you have tried to plant rise before it takes a lot of people. all right, so we talked about the past, and the present so i want to get specific and look at a case study. this will illustrate many of the points i have tried to discuss. this case study will be the oldest which is still persisting today then is bonded labor. so bonded labor, how did it work in centuries past? well, i provide an overview in my new book that just came out, i hope you guys get a chance to read it and send me your feedback. it is based on a credit labor agreement. what that means is in the past you had large numbers of landless pee zandted. so they had to borter their labor as a means of survival. these lasted for the lifetime.
